Not sure I necessarily agree with Bill Moyer's assessment, but he's a respected journalist with plenty of credible history.
Robert F. Kennedy Jr. has compelling evidence showing the current administration trashing current environmental laws in "Crimes Against Nature". It's on my reading list. A short article:

and a bit longer one in Rolling Stone:

As Kennedy says, we (Republicans, Democrats and others) all share the same interest in clean air, water, and taking care of wildlife and the commons (public lands).
Can anyone be against our environment? Well, yes. It's a matter of perspective, and the current administration seems to have their own.
